I like how easy this is for our accounting department so they don't need an app that's specifically designed just in order take payments over email from clients via their phone! It was difficult finding something out of box as we had too many options but now thanks PayPal (and other payment processors) there are more available platforms you could use which helps us streamline things even further.- Receipts management - Eases communication back into your office when someone takes money off invoice/receipr etc.
